Johnathan makes $24 in 6 hours, so how much would he make in 8 hours
suter [353]
$24 in 6 hours.

6 hours = $24

1 hour would be:  $24/6 = $4

8 hours would then be:      $4 * 8 = $32.

So he would make $32 in 8 hours.

Hope this explains it.

Answer

27 days

Step-by-step explanation:

father= 45 days

oldest son + father=27 days

youngest + father= 36 days

45-27=18

45-36=9

18+9=27

so it would take 27 days for both sons to complete the house

18 days=oldest son

-8x-27=-7\left(1+2x\right)+2x
Darina [25.2K]

Answer:

x=5

Step-by-step explanation:

-8x-27=-7\left(1+2x\right)+2x

Expand:

-8x-27=-7\times 1-7\times 2x+2x

-8x-27=-7-12x

Add 27 to both sides:

-8x-27+27=-7-12x+27

-8x=-12x+20

Add 12x to both sides:

-8x+12x=-12x+20+12x

4x=20

Divide both sides by 4:

\frac{4x}{4}=\frac{20}{4}

x=5

al dividir A entre 23 se obtuvo 247 de cociente y el residuo fue el maximo. hallar A a)5242 b)5436 c)5703 d)5332 solo esas 4 alt
yuradex [85]

Aplicando la división, hay que el valor de A es dado por:

c) 5703

Una división es representada por:

\frac{a}{b} = c + \frac{r}{b}

En que:

  • c es el cociente.
  • r es el residuo.

En este problema, b = 23, y también:

  • Cociente de 247, o sea, c = 247.
  • Residuo maximo, que es 22, o sea, r = 22.

\frac{a}{b} = c + \frac{r}{b}

\frac{A}{23} = 247 + \frac{22}{23}

A = 23(247) + 22 = 5703

El valor de A es dado por:

c) 5703
